7 Display part Figure 7-1 LCD panel structure LCD: it can query AC input voltage, AC input frequency, output voltage, output frequency, DC input voltage, ambient temperature, output load percentage and fault code; On/off: press the on/off key to start and shut down the machine; Page turning: realize the LCD page turning function through the page turning key; Operation indicator light: when the equipment works in battery state, the operation indicator light flashes;When the equipment works in the mains power state, the operation indicator light is on for a long time;When the equipment is abnormal, the operation indicator light is off; Alarm indicator:
when the equipment is abnormal, the alarm indicator will be on for a long time;When the equipment works normally, the alarm indicator is off;The fault type can be queried through LCD, and the comparison table is as follows Table 7-1: Fault type reference table 13 3.12 Output low voltage alarm ≤200 Vac Battery inverter 3.13 Heat dissipation mode Cooling with fan Intelligent speed regulation 4 Overall dimension:
